BUILDING BLOCK.

Application filed January 24, 1923. Serial No. 614,620.

T all whom it may concern:

Be it known that I, GLADYs E. WIGKSON, citizen of the Dominion of Canada, residing at Victoria, in the Province of British Columbia, Canada, have invented certain new and useful Improvements in Building Blocks, of which the following is a specification.

This invention relates to a hollow building block or tile, and is designed toprovide a light and serviceable block of this class that will have a full bedding face, and that will bond in a satisfactory manner. Further, the form of the block and the arrangement of its air spaces are such as will prevent the percolation of moisture through the thickness of the wall, not only through the material of the block, but through the mortar joints. The block has also the appearance in the wall of an ordinary brick.

The invention is particularly described in the following specification, reference being made to the drawings by which its is accompanied, in which:

Fig. 1 is a perspective view of the block.

Fig. 2 a similar view of a modification of the same. 7 i

Fig. 3 shows in perspective the application of the block to a single wall.

Fig. 4 shows in perspective an application of the block to a wall of double block thickness.

Fig. 5 shows the same in end elevation to illustrate the preferred amount of the vertical offset of the two parts of the block.

The block comprises two rectangular portions 2 and 3, each of which is lengthwise apertured or cored, as at at and 5, from end to end parallel with their bedding and ex ternal faces.

These portions 2 and 3 are connected together, with with the inner block 3 offset upward from the block 2, by walls 6, which extend angularly between the adjacent edges of the bedding faces of 2 and 3 to support these portions at a distance apart to enable an air space '7 to be provided from end to end between the walls 6 and the adjacent walls of 2 and 3. I

As made, thes connecting walls 6 extend from a position slightly below the inner edge of the offset bedding face to a position slightly less than that amount inside the bedding face from which the other is offset.

Ridges 8 project outward adjacent the their ends coterminous, and.

inner edge of the bedding face of each portion 2 and 3, which ridges interlock with those of the adjacent'block when the same is built into a wall, (see Fig. 3) and prevent the mortar from being expressed into the air space 9 which is retained b-y-these ridges between the walls 6 of adjacent blocks.

The block may mensions, but the length and the distance between the outer faces of each portion 2 and 3 will preferably conform to the length of a standard brick, and the depth of each portion 2 and 3 is either that of a standard brick, or double the standard brick thickness plus the mortar joint.

To ensure regular expression of the clay, when moulding, and uniform burning of the same, small lengthwise core spaces 10 may be introduced at the junction of the walls 6 to those of the portions 2 and 3. Where the blocks are of larger size, each core space 4 and 5 may be vertically divided by a longitudinal upright wall 11, as shown in Fig. 2.

In the use of these blocks they will preferably be arranged to have all the connecting walls 6 and their related air spaces 7 and 9 slope upward from the weather face. Fig. 3 shows a single block wall so arranged, and Fig. 4, a wall of multiple block thickness.

hen, as shown in Figs. 4: and 5, these blocks are built in a wall of greater than single block thickness, half blocks 12 are used in alternate courses, on the outer and inner faces of the wall only, in which case an air space 13 is retained opposite each alternate mortar joint.

The portions 2 and 3 of the block may be vertically offset any desired amount, but the offset of each block will preferably be half the depth of either portion 2 or 3 plus half the assumed thickness of the mortar joint. Thus, where two blocks come together, as shown, in the imier face of the wall in Fig. 5, the offset of the blocks op positely set plus their mortar joint will al low between them the full depth of the inner portion 3 of the block in the outer face of the wall with its two mortar joints.

The several advantages of this block are, that the bedding faces extend across the greater part of its horizontal dimensions, in distinction to other blocks of this class, where the core spaces are vertically disposed, and the blocks bed only on the thickness of the walls. Further, the vertical walls of this block are immediately over one anbe of any convenient diiii other, ensuring a. proper distribution of the weight. imposed on: the walL. 7

gain, the percolation of moisture from the outer or weather faces of the Wall is intercepted by the air spaces 4, 7 and 5 of each block, and by the air spaces 9 and. 13v between the blocks, and these latter air spaces 9 and 13 also intercept the percolation through the mortar joint. Further, both the connecting walls and the air spaces 7 and 9 between; them are, angled upward, which further tends tocheclr; percolation of lIlOlS t111(3*f10111utl16 weather exposed side of the walk to: the: other.

Having; now particularly described my invention,.I hereby declare that. what I claim asnew and desire to, be protected in by Bet-- tens: Patent, is:

2. A building block composed of integral hollow portions of substantially equal depth, connected together by parallel walls extending angulairly between the bedding faces of the hollow. portions to vertically 01T- set one portion of the block from the other, and ridges extending longitudinally along the face of said parallel walls adjacent to the upper and lower extremities of the'same lion thepunposes. specified.
